Officials are in a no win situation with you then. If they call too many fouls people say, "there's no flow to the game, the players can't get into rhythm, or my personal favorite LET THEM PLAY" BLAH BLAH.
If they swallow the whistle and let some stuff go, then all we hear is, "that's thug ball, its horrible." He's hacking him, its over the back (which is no such rule).
Every game is going to be officiate differently because some officials let the ticky tack stuff go and others call it. Those guys are under extreme pressure because they get reviewed for every call they make. So basically it "HAS" to be there in order for them to call it.
Iowa's problem is we have a "finesse" team and thats good when refs are calling fouls. Its not good when they let the little stuff go. Our team is not built to be physical or be bodied up against.
